Hi! Sorry for a late response! Did you try reconnecting to the network your Sonos speakers are on and then restarting the Flic app (menu -> exit)?
Also, make sure your speakers are first configured in the Sonos app. In the Sonos app where all your speakers are listed, make sure the speaker you want to trigger doesn’t belong to a user.
If you've tried all these steps it should work, but if you sill have issues send us an email at email@example.com
Let me know if you get it to work! :)
I have the same problem. My flic cant fond my sonos players. I have a sonos amp and a play 1, both connected to the same wireless network that my iPhone who runs the flic app is. First i thought i EAs a network problem, but then i noticed that i can find my Philips hue on the same network. Any ideas?
